Instructions
Enable step-by-step modeMake the blondies:
- Preheat your oven to 350°F. Line or grease your 8x8-inch baking pan.
- Brown the butter; add your butter to a saucepot. Cook over medium heat until it foams, and the butter becomes golden brown. It should have a nutty aroma.
- Mash the banana; mash the banana in a large heat-proof bowl using a fork or puree it with an immersion blender. Pour the butter straight from the stove over the banana. The banana will sizzle a bit.
- Mix the banana with butter and set aside to cool down to room temperature.
- Add the sugar; add coconut sugar, monkfruit sugar, egg, egg yolk and vanilla extract into the bowl with the banana.
- Whisk until fluffy.
- Add the flour; fold in the flour, baking soda, and salt. Stir until just combined.
- Add chocolate chips and stir to incorporate into the batter.
- Pour batter into the prepared baking pan. Bake the blondies for 22-25 minutes. Edges should be lightly golden, but the center should still be a bit soft. Set aside to cool to room temperature.
Make the frosting:
- Brown the butter; brown the butter over medium heat until it is foamy and has a golden-brown color. Set it aside to cool down to room temperature.
- Beat the cream cheese; add the cream cheese to a bowl and beat until fluffy. Add powdered monkfruit and arrowroot starch. Beat using a handheld or stand mixer until fluffy.
- Add the cooled browned butter and beat until you have a fluffy frosting.
- Immediately spread the frosting over the prepared blondies. Spread as you like.
- Refrigerate blondies for 1 hour before slicing and serving.
